The Aldrich House returns to Red Brook Harbor. Built in 1890 as a seaside retreat for Boston travelers arriving by train, the Cataumet landmark was fully restored in 2022 with all-new systems, whole-house generator, and an 18-bedroom Title V septic, the kind of permit Cape towns no longer issue. Across three stories, more than 7,000 SF of refined interior: an open great room with floor-to-ceiling stone fireplace, a chef's kitchen, original hardwood restored throughout, and wraparound porches that hold the harbor view. 10 en-suite bedrooms, each with private sitting room, kitchenette, independent climate control, and a balcony for Buzzards Bay sunsets. Outside, 1.84 manicured acres with in-ground pool, gazebo, and firepit. The home includes 3X Commercial Speed Queen dashers and dryers, and more. Family compound, private retreat, or boutique hospitality. Minutes from sandy beaches, Red Brook walking trails, the National Seashore, and the Islands ferries; and only 80 minutes from Boston.
ADU Potential
Massachusetts allows one accessory dwelling unit by right in single-family zoning districts statewide (M.G.L. c. 40A §3; 760 CMR 71.00, effective Feb 2025). Estimated maximum ADU size for this property: 900 sq ft (the lesser of 900 sq ft or half the 7,560 sq ft principal dwelling). Lot size: 80,150 sq ft.
Based on listing data, which indicates the property type — not the zoning district. Local dimensional, septic (Title 5), and historic-district requirements still apply. Not legal advice — verify with the municipality.
Estimates — not financial advice
These figures are illustrative estimates for informational purposes only — not an appraisal, valuation, or guarantee of rent, income, or returns, and not financial, tax, or investment advice. Rent is either the figure reported on the MLS listing — in-place rent that may differ from market and is not verified against the actual leases — or, where the listing reports none, an estimate from HUD Small Area Fair Market Rents, a government benchmark that may differ from actual market rent. Each figure is labelled with its source. Cap rate, NOI, and returns depend on the assumptions shown, which you can change. MLS and other third-party data may be inaccurate or out of date. Verify all figures independently and consult your own financial, tax, and legal advisors before making any investment decision.
